Boron Nitride Nanotubes (70% purity)



Boron Nitride Nanotube is a next-generation Nano-material which will lead the 4th industrial revolution. Boron nitride nanotubes (BNNTs) are another form of boron nitride. Structurally they are nano-cylinders with sub-micrometre diameters and micrometre lengths. They are composed of hexagonal boron nitride, constructed by combining boron and nitrogen.

The key features that represent BNNTs are light weight, mechanical strength, thermal and chemical stability, high electrical resistivity and neutron absorption capacity.
